Abstract (en)
[origin: WO0186182A2] Methods and apparatuses for rehabilitating and increasing the functionality of existing underground conduits wherein a plurality of conduits are simultaneously inserted into an existing conduit by bursting the existing conduit to create a tunnel and inserting a plurality of new conduits into the tunnel, such that at least one of the new conduits has a capacity equal to or greater than the capacity of the existing conduit, are provided. The new conduits are either separate from or removably connected to one another, such that the new conduits are capable of being diverted from the tunnel at separate locations and the new conduit system can be used primarily for carrying media similar to that of the original conduit or additionally for completely different and unrelated media such as fiber optic cable, coaxial cable or electrical cable.
